“…e muscle provides both passive stabilization and dynamic stabilization of the glenohumeral joint, buttressing the joint from a posteriorly directed force. e upper segment of the muscle has been shown to be more involved with internal rotation, while the lower segment can help in external rotation while the arm is abducted [7][8][9]. ese portions of the muscle and their corresponding tendons are each innervated by the superior and inferior subscapularis nerves, a branch of the posterior cord of the brachial plexus [10].…”

“…Failure to repair a concomitant subscapularis tendon tear has been found to compromise the normal biomechanical function of the tendon as described above and potential compromise of an associated posterosuperior rotator cuff tear repair [ 25 , 26 ]. Chronically torn tendons undergo muscular atrophy and fatty degeneration, which have been described as negative predictors for a successful surgical repair [ 4 , 8 , 19 ].…”

As the largest rotator cuff muscle, the subscapularis plays a major role in stabilizing the glenohumeral joint, in conjunction with surrounding rotator cuff structures. Injury to the subscapularis tendon can be isolated, but more commonly is seen in conjunction with supraspinatus tendon pathology. Injury can be associated with biceps pulley instability, superior labral anterior-posterior (SLAP) tears, humeral head subluxation, and anterosuperior and coracoid impingements. The involvement of the rotator interval can lead to what is called “the hidden lesion,” due to its difficulty to diagnose during arthroscopy. Understanding the anatomical relations of the subscapularis tendon with the rest of the rotator cuff and rotator interval, as well as common patterns of injury that involve the subscapularis tendon, can aid in proper diagnosis of these injuries leading to prompt surgical repair. This review describes the anatomy of the subscapularis muscle and tendon, and the magnetic resonance imaging (MRI) patterns of subscapularis tendon injury.

“…The display of such information in the cross-sectional, sagittal or coronal planes provides the power of 360˚visualization of the region of interest. Furthermore, we harness the power of simultaneous multi-mode high resolution ultrasound imaging where data are collected for Bmode (anatomy and elastography) as well as color Doppler flowmetry [15][16][17]. The major constituents of cutaneous extracellular matrix proteins mainly collagen and elastin contribute to biomechanical properties of the skin.…”

High resolution ultrasound imaging for repeated measure of wound tissue morphometry, biomechanics and hemodynamics under fetal, adult and diabetic conditions

et al. 2020

Non-invasive, repeated interrogation of the same wound is necessary to understand the tissue repair continuum. In this work, we sought to test the significance of non-invasive high-frequency high-resolution ultrasound technology for such interrogation. High-frequency high-resolution ultrasound imaging was employed to investigate wound healing under fetal and adult conditions. Quantitative tissue cellularity and elastic strain was obtained for visualization of unresolved inflammation using Vevo strain software. Hemodynamic properties of the blood flow in the artery supplying the wound-site were studied using color Doppler flow imaging. Non-invasive monitoring of fetal and adult wound healing provided unprecedented biomechanical and functional insight. Fetal wounds showed highly accelerated closure with transient perturbation of wound tissue cellularity. Fetal hemodynamics was unique in that sharp fall in arterial pulse pressure (APP) which was rapidly restored within 48h post-wounding. In adults, APP transiently increased post-wounding before returning to the pre-wounding levels by d10 post-wounding. The pattern of change in the elasticity of wound-edge tissue of diabetics was strikingly different. Severe strain acquired during the early inflammatory phase persisted with a slower recovery of elasticity compared to that of the non-diabetic group. Wound bed of adult diabetic mice (db/db) showed persistent hypercellularity compared to littermate controls (db/+) indicative of prolonged inflammation. Normal skin strain of db/+ and db/db were asynchronous. In db/db, severe strain acquired during the early inflammatory phase persisted with a slower recovery of elasticity compared to that of non-diabetics. This study showcases a versatile clinically relevant imaging platform suitable for real-time analyses of functional wound healing.

“…The subscapularis (SSC) is a triangular shaped muscle within the subscapular fossa (Standring, ). It is the largest and most powerful of the rotator cuff muscles for maintaining shoulder stability and the motion of the glenohumeral joint (Alilet et al, ). Several pathologies are associated with the SSC, such as tendon tears, calcific tendinitis, subacromial bursitis, recurrent anterior instability of the glenohumeral joint, and large rupture of the rotator cuff muscles.…”

A Detailed Analysis of the Blood Supply to the Subscapularis Muscle

This study aimed to provide a comprehensive description of the arterial supply to the subscapularis (SSC) muscle. This will provide critical information for various surgical procedures. Ten specimens of embalmed Korean cadavers were dissected and subjected to modified Sihler's method to reveal the branching pattern of the arteries surrounding the subscapularis, and its intramuscular blood supply. The SSC muscle was generally supplied by branches from the subclavian artery (suprascapular artery, supraSA; circumflex scapular artery, CxSA; and dorsal scapular artery, dSA) and the axillary artery (subscapular artery, subSA; lateral thoracic artery, LTA; posterior circumflex humeral artery, PCxHA; and a branch of the axillary artery, AAbr). The anterior aspect of the muscle was supplied by the subSA, LTA, CxSA, supraSA, and AAbr. The posterior aspect of the muscle was supplied by the supraSA, PCxHA, and subSA. The dSA was more scarcely distributed than the other arteries. In two cases, the dSA supplied the portion of the muscle near the medial border of the scapular. The anterior side of the muscle tendon was supplied by the CxSA, and its posterior side was supplied by the PCxHA. The subSA can be considered to be the main branch supplying the SSA based on its distribution area of arteries. It was mostly situated within the lower region of the SSC. After distributing to the anterior surface of the SSC, some branches of the subSA reached the posterior surface as perforating branches. Clin. Anat. 32:642–647, 2019. © 2019 Wiley Periodicals, Inc.
